Sounds like a great way to get your Google account banned for a suspicious activity.
This is a separate google drive provisioned specifically to be used via API through google cloud
I think Google Cloud has a Google Drive API for such use cases
What's the criteria to get a google account banned?
I don't think even people working at abuse detection at Google know the criteria. It's just AI.
Probably the fact that it sort of takes advantage of google as a free backup service
